Do you have a chance to set the boot options and perhaps the splash to verbose or text? If so, you should see where it stops. Some CD's like this will continue to loop over and over again with just the splash up. Several times I've had issues with Ubuntu and Mandriva where it can't mount FD0...because I don't have it enabled nor do I want it. Enable it, goes right on by and continues.
I'd also run it through a VM and see if it boots. Either that or check the disk quality or the MD5 checksum.
If this is a first run with nix, this isn't a good taste left in the user's mouth. Having something not work doesn't even let you tinker, Live CD or not. Just about every time an install or Live run doesn't work, it boots right up within VirtualBox. Then at least you can look around in a new OS and figure it out later. I mean, mounting, the drive paths (hda vs. C:\), and other terms are better connected to known terms just by running around in nix. THEN the install and all that makes a little more sense.
Was this typical for you guys too early on?
Most distros do not offer what UBUNTU offers - running its feature and function from bootable CD... and ability to test and see if you like it before performing actual install.
Mandriva08.1 Spring Live CD...my fav lately!
Which I'd give a shot here too. Many love Ubuntu, but to me it's from over recommendation. A new person uses it, then sticks with that as THE nix distro and recommends it as such. I see nothing wrong with Mandriva for a new user and vet alike. Or Gentoo, Suse, or FreeBSD for that matter. Feet first, right?
